We had several of them - but all of them had at least one of the read making major distortion / screeching sounds, which means we would have to finish the setup of the instrument to use it properly. Also it leaks a bit of wind in most versions.

We ended up returning all the products and going to another shop - the product looked the same but did have a quality control there - made the difference for us.
